У меня есть условие монетного двора (почти ~24h без любых изменений руководства, только склонных - получают установку), гном человечности 14.04.2 установленных.

Поскольку я должен смочь использовать pyqt5, который зависит от qt5-значения-по-умолчанию, которое зависит от gt5base-dev, я задавался вопросом, как я могу зафиксировать эту ситуацию?

Я могу установить старые версии пакетов?
